Abstract

Situ Sipatahunan serves as a source of irrigation, a tourist attraction, and a provider of domestic drinking water, making it important to the community of Baleendah. Monitoring water quality is necessary to detect potential pollution and ensure its suitability in supporting these functions. Phytoplankton is used as a bioindicator because it is sensitive to environmental changes. This study aims to assess the water quality of Situ Sipatahunan based on the phytoplankton community and its relationship with the physical and chemical parameters of the water. Sampling was carried out at three stations using purposive sampling based on different environmental conditions, using a 400 µm plankton net. 25. Data analysis used abundance, diversity, evenness, dominance, saprobic indices, and correlation tests. The results showed that there were 44 phytoplankton species in the waters of Situ Sipatahunan, consisting of the classes Bacillariophyceae, Chlorophyceae, Cyanophyceae, Dinophyceae, Xanthophyceae, Euglenophyceae, and Rhodophyceae. Abundance ranged from 855 to 1096 cells/L/L. Diversity levels were moderate (1.79–1.94), evenness was moderate (0.60–0.69), and dominance was low (0.22–0.29). There is a significant relationship between nitrate and phosphate levels and the level of phytoplankton diversity. Water quality is classified as β–Meso/oligosaprobic or lightly polluted.

Abstract

Creative thinking is an essential 21st-century skill that enables students to approach complex problems with originality, flexibility, and depth. However, its development in Indonesian science classrooms remains limited. This study analyzed junior high school students' creative thinking profiles on the digestive system using Torrance's framework, which includes fluency, flexibility, originality, and elaboration. A total of 108 eighth-grade students in Bogor participated in the study. Data were collected through essay tests and semi-structured teacher interviews and analyzed using descriptive statistics and thematic analysis. Results revealed a low level of creative thinking, with an average score of 36.75%. Originality scored the highest (43.58%), while flexibility was the lowest (30.66%). Students showed difficulties generating multiple ideas, viewing problems from different perspectives, and developing ideas in detail. Teacher interviews confirmed that creative thinking was not explicitly taught, and procedural tasks mostly dominated learning activities. This study offers insight into how biology learning environments can reveal the strengths and gaps in students’ creative thinking. The findings are expected to inform future learning designs that aim to foster creativity and critical thinking in science education and may serve as a basis for integrating STEM-oriented approaches more effectively.

Abstract

Future biology educators face a unique challenge when creating learning modules for Education for Sustainable Development (ESD): they must seamlessly fuse core biological science with broader sustainability values. To understand what drives success in this complex task, we explored how two internal factors—Habits of Mind (HoM) and Perceived Teacher ESD Competency—shape the way pre-service teachers craft their instructional designs. We approached this through an explanatory sequential mixed-methods framework. Initially, we gathered quantitative survey data from 49 prospective teachers in Indonesia. Building on those baseline numbers, we then dove deep into the qualitative experiences of nine selected individuals by analyzing their module documents, reflective journals, and semi-structured interview transcripts. Our statistical modelling showed a strong relationship: together, these cognitive and psychological traits accounted for 64.3% of the differences in module quality (R^2=0.643, p

Abstract

Dura mater is a protective layer that surrounds the brain and spinal cord. Damage to the dura mater caused by trauma, neurosurgical procedures, or infections can lead to cerebrospinal fluid leakage and other complications. This study aims to develop a biomaterial-based dural patch from bacterial cellulose (BC) reinforced with chitosan and Piper betle leaf extract. BC was synthesized using Acetobacter xylinum in a coconut water medium, soaked in a chitosan solution with varying concentrations of Piper betle extract (0%, 5%, 10%, 15%), and dried using the freeze-drying method. The material was characterized through FTIR analysis, swelling tests, degradation tests, and antibacterial tests. The results showed successful composite synthesis, indicated by functional group interactions between BC, chitosan, and Piper betle extract. The highest swelling ratio was observed in the control sample (1002%) and decreased significantly in the 15% extract concentration (446%). Degradation tests revealed that the addition of Piper betle extract increased the degradation rate, with ANOVA results (p = 0.0429) indicating significant differences. Antibacterial tests showed an increased inhibition zone against S. aureus (0–5.4 mm) and E. coli (0–2.2 mm) with higher extract concentrations. These findings suggest that the BC-chitosan composite with Piper betle extract demonstrates potential as a dural patch with antibacterial properties, swelling capability, and degradation rates suitable for biomedical applications.

Abstract

This study aimed to develop an Argument-Driven Inquiry (ADI) and Socio-Scientific Issues (SSI)-based digital worksheet on environmental change by integrating authentic local environmental issues from Gorontalo. The novelty of the developed worksheet lies in the integration of ADI as the inquiry and argumentation sequence, SSI as the contextual basis for examining environmental problems, and the Claim–Evidence–Reasoning (CER) framework as explicit scaffolding for constructing scientific arguments. This research employed a research and development design using the ADDIE model, limited to the analysis, design, and development stages. The participants consisted of one biology teacher and 35 Grade X students at SMAN 1 Dungaliyo, Gorontalo Regency. Data were collected using needs analysis questionnaires, expert validation sheets, and practicality questionnaires, and were analyzed using descriptive quantitative and qualitative techniques. The expert validation results showed that the digital worksheet was highly valid, with an average score of 96.00%. The teacher practicality score was 96.00%, while the student practicality score was 93.79%, both categorized as very practical. These findings indicate that the worksheet is initially feasible as supplementary teaching material for environmental change learning. This study contributes a structured digital learning resource that connects local environmental issues with inquiry activities and CER-based scientific argumentation. Further studies are needed to examine its effectiveness in improving students’ scientific argumentation, critical thinking, and environmental awareness.

Abstract

The limited time available to deliver the “Fungi and Their Roles” topic and the lack of classroom materials to support its learning are obstacles that can hinder holistic biology learning. An e-module integrated with local mushroom diversity is one option for learning media that can support contextual learning on fungi. This research aims to assess the feasibility of an e-module on mushroom diversity in the Sebubus Forest, Sambas Regency, as an innovative and contextually relevant biology learning medium. The applied research and development method used the Define, Design, Develop, and Disseminate (4D) model, limited to the third stage. The e-module was validated by five validators using five assessment criteria. The results of the validation data analysis showed that the five assessment criteria obtained a Content Validity Ratio score of 0.99 and were considered valid. The Content Validity Index score based on the five criteria was 0.99, which is the threshold, indicating that the e-module on mushroom diversity in the Sebubus Forest, Sambas Regency, is valid and suitable for learning, especially in the topic of “Fungi and Their Roles.” By leveraging local biodiversity, this e-module is expected to enhance students’ understanding of fungi, particularly mushrooms, and their diversity.

Abstract

Kotok Bongkok is a fermented local dish from Lebak Regency, Banten, using seeds of kluwek (Pangium edule) via fermentation method by boiling the seeds, peeling the seed skins, soaking in mountain spring water, and fermenting naturally in bamboo. This research attempts to study the local knowledge of communities on the process of making kotok bongkok and determine the type of fungi used during the fermentation process. The data were collected based on field observation, informal and semi-structured interview on 92 informants, as well as identifying the fungi characteristic by morphological and microscopic isolation. The findings reveal that women, especially teenagers age 15-17 years old, dominantly preserve the knowledge on how to make kotok bongkok. The fermentation process creates an exclusive taste and decreases cyanide considerably. Preliminary identification on microbiology analysis shows dominant fungi that exist during fermentation process are Mucor racemosus, Rhizopus oligosporus, and yeasts which create specific aroma on the product. Based on proximate analysis, this fermented product has high content of fat and moisture, followed by protein and fiber. This study emphasizes that Kotok Bongkok is a biocultural heritage that unites biological and cultural aspects, and it has the potential to be developed as an innovative food product based on local wisdom to support food security and green economy principles through community empowerment, and the preservation of Indonesia’s culinary identity.
